Kevin Jetton, CIS 3380 Exam 3,(Ch 9, 13-19) & (BPI 4,5,9,11)
Ch 13 K.I.D- Disruptive .vs. Sustaining Technology - Answer - Disruptive technology - A
new way of doing things that initially does not meet the needs of existing customers
• Computing: Mainframe, Mini, 1st PC's, SmartPhone, Tablet
• Sharing/Service Economy: Lyft/Uber/AirBnB, Instacart
• Product Sales: Online, eBay, Amazon...
• 3-D printers
- Sustaining technology - Produces an improved product customers are eager to buy
• Electronic Storage Media (Floppy Drives, CD, USB, Cloud)
Ch 15 K.I.D- Open Systems/Open Source - Answer ▪Open system - Nonproprietary
hardware and software based on publicly known standards that allows third parties to
create add-on products to plug into or interoperate with the system
❖ Source code- Contains instructions written by a programmer specifying the actions to
be performed by computer software.
❖Open source- Any proprietary software licensed under exclusive legal right of the
copyright holder.
❖ Closed source- Any proprietary software licensed under exclusive legal right of the
copyright holder
BPI 5 K.I.D- VoIP - Answer Voice over IP (VoIP) - Uses TCP/IP (Transmission Control
Protocol/Internet Protocol)technology to transmit voice calls over long-distance
telephone lines
BPI 5 K.I.D- IPv4 .vs. IPv6 - Answer IPv4- ran of Ip adress #'s. 32-bit number: 4 billion
addresses (2 32
, IPv6- 128-bit addresses, able to handle up to 1 quadrillion address
the main differnece is that IPv6 is a much larger adress space that allows greater
flexibililty in assigning adresses
Ch 16 K.I.D- Wireless Security Threats - Answer 1. Rogue access point- is an
unauthorized access point to a wireless network.
2. Eavesdropping- refers to efforts by unauthorized users to try to access data traveling
over wireless networks - Encryption, Packet "Sniffing", ID Theft, Db/CrCard Fraud
3. RF (Radio frequency) jamming- is when a person or a device intentionally or
unintentionally interferes with your wireless network transmissions. (Hotels, Convention
Centers)
Ch 17 K.I.D - SDLC Phases - Answer ▪Systems development life cycle (SDLC) - The
overall process for developing information systems from planning and analysis through
implementation and maintenance
1. Planning phase - Establishes a high-level plan of the intended project and determines
project goals
2. Analysis phase - Involves analyzing end-user business requirements and refining
project goals into defined functions and operations of the intended system
3. Design phase - Establishes descriptions of the desired features and operations of the
system including screen layouts, business rules, process diagrams, pseudo code, and
other documentation
4. Development phase - Involves taking all of the detailed design documents from the
design phase and transforming them into the actual system (Coding)
5. Testing phase - Involves bringing all the project pieces together into a special testing
environment to eliminate errors and bugs, and verify that the system meets all of the
business requirements defined in the analysis phase
6. Implementation phase- Involves placing the system into production so users can
begin to perform actual business operations with it
